Application filed May 2l, 1904. Serial No.y 209,048. l

Be it known that I, FREDERICK J. MoTz, a citizen of the United States,and a residentor1 the city of New York, borough of Manhattan, in thecounty of New York and State of New York, have invented a new andlmproved Machine for Making Paper Articles, of which the followingisafull, clear,and exactdescription.

My invention resides in a certain novel machine by which seamless paperarticles may be produced, the machine being of that form having a vatand means for automatically submerging foraminous shapes therein andwithdrawing them therefrom and exerting through the shapes a Huidmovement during the time of their submergence, thus causing the pulp toadhere to the shapes, so that after they are withdrawn from the vat thepulp may be allowed to harden or set on the shapes to form the finishedarticles.

I will nowspecilically describe the preferred embodiment of myinvention, reference being had to the accompanyingdrawings, formingapart of this specification, in which4 Figure 1 is a longitudinal sectionof the machine. Fig. 2 is a cross-section thereof. Fig. 3 is an enlargedsectional view of one of the suction-heads, showing one of the shapesengagei'l therewith and illustrating the automatic action of thesuction-cut-off valve. Fig. 4 is a detail perspective view showing thepreferred manner of forming the shape and illustrating' the manner inwhich the pulp accumulates thereon, and Fig. 5 is a detail of one of thespring-closed valves.

10 indicates a vat Vfor containing the pul p, which is supplied to theupper part of one end thereof through a pipe or conduit 11. 1n said -vatis arranged a horizon tal partition 12, forming a false bottom andhaving at each end a vertical partition 14. Said partitions 12 and 14are in watertight engagement with the .sides of thevat and form,therefore, a continual or endless passage through which the pulp may becirculated in the manner indicated by the arrows in Fig. 1. 15 indicatesany desired form of pump-for instance, a ifan-puml) for maintaining thiscontinual circulation of the pulp, by which means the pulp is kept at aneven consistency and the solid parts thereof preventedfrom settling inthe bottom of the Vati 16 indicates aplugor eq'uivalen'tconnection fordraining the vat. Mounted onthe sides of the vatarerboXes 17, in whichare mounted to turn the journals 18 of a suction-drum 19.

2O indicates a suctionpipe Vextending through one of the trunnions 18,whichishole lowed for this purpose Aand projects downward into thesuction-drum. Said pipe 20 is adapted to have communication with anysuitable vacuum-forming apparatus, so as to exert a continual suctionwithin the drum 19. The remaining or solid journal 18 of the drum 19 hasfastened thereto a pulley 21, by which` means or by any other meanssuitable forthis purpose a continual rotary movementlma-y be given tothe drum.v As here shown, the pump 15 is driven also by abelt connection22 from the said remainingjournal of the suctiondi'um 19. v

Communicating with the interior of the suction-drum 19 and passingradially there-A from are a number of stout tubes 23, each provided witha Valve 24, having a spring 24L or other suitable means for normallyholding them closed. (See Fig.

e.) The valves 24 also have operating' lingers or handles- 25, in thepath of which is arranged a segmental track 26, suitably supported atone side ofthe tubes 23 by any desired means-for example, by the rods26. (Best shown in Fig. 2.) One end. of the track 26 is located j ustabove the upper edge of the vat 10, while the opposite end is locatedsome distance above the top of the Vat. The drum 19, with itsattachments, is intended to turn toward the lirst-named end of thetrack, as indicated by the arrow in Fig. 1, and the result, therefore,of the peculiar arrangement of the track and its l relation to theoperating fingers or handles 25 of the valves 24 is that as the tubes 23dip into thef vat the handles 25 strike the low end of the opened,allowing the suction within the drinn 19 to be exerted through thepipes"23."" This'- condition continues as the tubes inove'throughy thevat and until the tubes rise above 'the'vat sufficiently to cleartheoperating arms or han i o'e d les of the valves 24 from engagementwith The special advantage of this operation will 1 be set forthhereinafter.

4 Each suction-tube 23 carries at its outer end a-suction-head 27.rlhese heads are, according to the form of the invention hereillustrated, essentially pan-shaped and provided with broad edges ormarginal faces 28. (Shown best in Figs. 2 and 3.) The outer ends of thetubes 23 at the points where they open into the suction-heads 27 arecommanded by sliding cut-offs 29. Said cut-offs are connected to stems30, and the stems have springs 31, applied so as to keep the cut-offsnormally active. The inner ends of the stems 30 are turned laterally, asindicated at 32, and project through openings 33 in the faces 28 of thesuctionheads, so that when the shapes are placed in position on thesuction-heads, as will be hereinafter fully stated, the cut-offs 29 willbe automatically moved to open or inactive position. 1n order tostrengthen the machine and also toassist in holding the shapes inposition,- I provide two annular bands 33, fastened suitably to theSideedges of the suction-heads 27 and formed with radial slots 34, theslots lying respectively in transverse line with the faces 28 of thesuction-heads 27.

,-The shapes or forms may be of any size and contour desired., thisbeing dependent upon the shape of the article to be formed, and a numberof shapes of different sizes and forms may be used in the machine at thesame time. As here illustrated, each of the shapes comprises a framingmade up of a relatively coarse wire mesh 35, with a binding 36 of wireor the like. Over said mesh is arranged a liner screen 37, of suitablemetal, the screen 37 being that on which the paper article is formed Iand its shape being that which it is desired to give said article.-

In Fig. 4, a, may be taken to indicate the pulp as it gathers on thescreen 37 during the formation of the article within the vat. Each shapeis also provided at its upper side with a hook 38, adapted to engageover the outer edge of the suction-head to which the shape is applied,thus holding the shape in position. The shapes are also provided withlaterallyprojecting studs 39, which may, il desired, be formed ascontinuations of the bottom bindingbar 36, the said projections 39 beingadapted to engagein the slots 34 of the bands or plates 33, thus guidingthe movements of theshapes when engaging with and (.lisengaging from themachine and assisting in holding' the shapes properly in position.Reference to Fig. 3 will show the relative position of the shapes andsuction-heads when in operation, from which it will be seen that thevhooks 38 engage the outer ends of the suction-heads, while the innerportion of the binding36 of the shape engages the projected part 32 of'the valve- Stem 30, thus moving the cut-oli' valve 39 to inactiveposition, as explained. This movement of the cut-off takes place theinstant that the shape is inserted into the machine, and a closingmovement takes place by the operation of the spring 31 the instant thatthe shape is removed from the machine. lt will also be observed that thebinding 36 or the edge of the shape bears around the broad face 28 ofthe suction-head, forming an essentially hermetic connection therewith,the effectiveness whereof is increased immediately after the inceptionof the operation by the accumulation of pulp around the edges of theshape. 40 indicates a suitable frame or superstructure which is erectedon the vat and which together with the side walls of the vat support thetwo guides 4l in which the projections 39 run and by means of which theshapes are automatically moved into proper position on the suction-headsand out of the same. The said guides 41 extend from the top of thesuperstructure 4() tangentially toward the wheel formed bythesuction-heads, tube, and drum and inward to the inner edges of thesuction-heads, at which point the guides take a circular courseconcentric to the journals 18 and pass downward into the vat and upwardout of the same and finally extend from lthe rotating wheel tangentiallyupward to the top of the superstructure. Two of these guides areprovided, one being arranged at each side of the wheel, and the guidesare preferably channel-shaped in crosssection, so as to receive andproperly hold the projections 39.

1n the organized operation of the machine the shapes are introducedbetween the righthand ends of the guides, (assuming that the wheel isturning in the direction indicated by the arrow in Fig. 1,) with theprojections 39 engaged in the grooves inthe guides. The shapes will dropdown between the guides until the projections 39 enter two of the slots34, whereupon the shapes will move with the wheel and will besimultane'ously run downward between the guides until the concentricportions of the guides are reached by the projections-39, whereupon thehooks 38 will engage the outer ends of the suction-heads, and this,together with the engagement between the projections 39 and the innerend of the slots 34, will arrest further independent movement of theshapes. As the shapes take this position they engage the parts of thestems 30 and automatically open the cut-ol'ls 29. I t should benotedthat suction cannot be exerted through the heads 27 until thevalves 24, corresponding with the heads, are opened. The rotation of thewheel is continued until the shape is submerged in the vat, and at thisperiod the handle 25 of the valve 24, corresponding to the said shape,strikes the track 26, and said valve 24 is opened. -Suetion is thenexerted through the head v27, tube 23, and drum 19, and the water isdrawn through IOO IOS i IIO the for'aminous shape, this current causingthe solid parts ot' the fiber to cling to the foraminous shape and Vforma covering oi' a size and form corresponding to that of the shape. Theshape continues this movement through the vat and finally rises at theother side. lt should be observed, however, that the suction is not cutoii until the valve-handles 25 disengage the high end of the track 26.

This allows a certain period during which at-l mospheric air is drawn bysuction through the shape and layerof pulp thereon,thus effectivelywithdrawing from the pulp all surplus liquid and leaving the pulprelatively solid on the shape. When the high end of the track 26 is leftby the valve-handles 25, the projections 39 of the shape begin to runinto the second eccentric or tangential ends of the guides and arethereby caused to move outward until'linally they are completelydisengaged from the wheel, as Fig. 1 illustrates. At this time thecutoff 29 will be allowed to become active, and the suction-pipe 23,corresponding to the shape thus moved out of engagement with thesuction-head, will be closed. .In connection with this cut-01T device itwill be seen that while the valves 24 actually control the beginning andend ot' the suction period the valves or cut-offs 29 prevent breakingthe partial vacuum or sucking the pulp into the suction-drum 19 shouldone of the shapes miss its position in the machine or should it becomedisplaced therein. The shape with the pulp clinging thereto, asexplained, should now be dried and the pulp allowed to set, thus forminga linished seamless paper article corresponding' accurately to the shapeon which it was produced. The pulp which is run into the vat is beatenand prepared in the manner usual for paper-making' and is then Alurth'ermixed with water to adensity of approximately two to three parts ot'pulp to one thousand parts oi' water. The Afiow ot' the pulp into thevat should be regulated so as to keep the level ot' the mixture thereinclose to the upper edge oi the vat.

l provide means for automatically taking' the shapes with the pulpclinging' thereto from the machine, transljiorting the shapes to asuitable means Vlor artiiicially drying the pulp and for disengaging thelinished paper articles from the shapes and then returning the latterinto the machine, thus allowing the operation ot' `forming' the paperarticles to go on continuously and avoiding the necessity oi' manuallyhandling' either the shapes or the paper articles during the period offormation. According to the form of the invention illustrated in thedrawings this means for automatically handling' the shapes comprise anendless carrier running over the top of the superstructure 4() andformed oli two endless chains 42 with transverse rods 43 pivotallymounted on the links thereof. Said rods are provided with hooks 44,adapted to engage in openings 38a, formed in the hooks 38. hooks 44 arealso provided with projecting iingers 45, adapted at a certain point inthe path of the carrier t`o strike a wedge-like detent 46, thus throwingback the hooks 44 and allowing them to disengage from the walls in theorifices 38. As the carrier moves in the manner indicated in Fig. 1 itshooks 44 successively engage in the oriliees 38 of the shapes as theyare successively raised from the wheel by the eccentric or tangentialform ot' the guides 4l. The shapes with the pulp adhered thereto arethen moved by the carrier into the drying-room or other means forartificially drying the pulp. rlhe carrier moves continuously throughthe drying-room, and the arrangement is such that when the upper run ofthe carrier passes from the drying room or apparatus the pulp will beset or hardened, thus forming the Finished seamless article. At asuitable ppint a blower 47 is located, which causes a blast of air to beforced through the foraminous shape and to-impinge against the iinshedarticle thereon, thus blowing the article from the shape and completingthe operations on the article. The carrier in continuing its movementadvances the shapes into\position to reenter the machine, and at thispoint the finger 45 strikes the said detent 46 and causes the hook 44 torock backward, thus automatically releasing the shape. Various otherdevices may be provided for automatically removing the shapes vfrom andengaging them with the machine, and in this connection l would mentionthat the shapes may be attached either permanently or removably to acarrier chain or chains which. are preferably endless and whlch are runwith.

the shapes through the guides 4l, these chains, therefore, moving theshapes continuously through the machine out to the d rying-room or otherdrying means and thence back into the machine, thus maintainingcontinuous operation and insuring' rapid work.
